FIRELESS COOKER.

Application filed January This invention relates to tireless cookers andmore particularly to that form of fireless cooker in which an electricheating unit is employed. 1 Further objects of the invention will beapparent from the specification and drawings in which- Figure 1 is avertical sectional view of my improved fireless cooker, v

Figure 2 is an enlarged detail view show ing the manner'in which themetallic hoods are sealed upon the base of the fireless cooker,

Figure 3 is a plan view of the base of the cooker,

Figure 1 is a sectional view of the hoods along the line 4-4 of Figure5, and

Figure 5 is a perspective View of the entire cooker assembled.

1 and 2 indicate concentric metallic hoods of varying diameter insertedone over the other, which are joined to each other by the heatinsulating members 3 and 1, the insulating members 3 and 4 beingfastened by means of the rivets 5. 6 is a non-metallic handle by whichthe hoods 1 and 2 may be lifted off of the cooker together. Theinsulating members 3 ands should be made of bakelite, wood or othernon-metallic material which will not give off any cooking odors. I

An important feature of this invention is the metallic base of thecooker 7 which preferably is made of one piece having depressions at 8and 921s shown, in which the hoods 1 and 2 fit. It will be noted fromthe enlarged detail of Figure 2 that the hoods 1 and 2 fit snugly intothe depressions in the base 7 on the inner and not on the outer edges ofthese depressions. The heatiil inc unit 10 havin the resistance wire 11isv inserted in the center of the base 7 and it should be noted that theheating unit is I itself made of an insulating material such asporcelain in which the heating wire 11 is embedded so that the porcelainbase of the heating unit itself acts as a non-conductor and the heat istransmitted upwardly only. The base 7 is riveted to a wooden stand 12,the current being transmitted to the unit through the aperture 13, aswitch 14% serving to turn on and shut off the cur rent.

Another feature of this invention are the depressions 15 and 16 in thebase 7 which 16, 1925. Serial No. 2,935.

depressions serve as outlets for any water which may be condensed in thegrooves of the base 17 or 18. An objection to many forms of tirelesscookers is-that the steam which is developed recondenses and fallseither upon the heating element or back into the food, whereas with theoutlets 15 and 16, any water which falls into the grooves 17 or 18 willnaturally run out of the cooker and cannot be reabsorbed into the food.

The cooking pot is, of course, placed upon the heating unit andpreferably covers the same, so that any water evolved in cooking willtend not to fall upon the heating unit but 011 to the base 7. spacebetween the hoods 1 and 2 and the air space under the base 7 serve as anexcellent heat insulator, so no other heat insulation said base andsubstantially level with the bottom of the innermost hood. I

2. In a fireless cooker, a series of concentric hoods seated upon acommon base so as to enclose a non-conducting air space between saidhoods, a base constructed of a single sheet of metal having a number ofgrooves therein to seat said hoods, a nonconducting enclosed air spacebeneath said base and an electric heating unit located in said base andsubstantially level with the bottom of the innermost hood, and openingsin said base for conducting away any waters The continuous air isrequired in this type of cooker.

of condensation evolved from the interior in to seat said hoods, saidbase having a nonconducting enclosed air space beneath same, an electricheating unit positioned in the center of said base, said heating unitbeing sub stantially level with said base and with the V v bottom of theinn rmost hood.

4. In a fireless cooker, a series of conpression, said electric heatingunit being centric hoods seated upon a common base so substantiallylevel with said base and with as toenclose a non-conducting air spacebethe bottom of said innermost hood. 11 tween said hoods, a metal basehaving In testimony whereof I hereuntoaflix my grooves therein adaptedto seat said hoods; signature; 7 a depression in the center of said baseand l 7 an electric heating unit located in said de; 7 HUGO MOGK.
